To allf'whom it may concern: f .l

Beit known that I, CHESTER T. BANGs, a citizenof the United States 'ofAmerica, and av resident of Chicago, in the county of Cook' and State ofIllinois, have invented certain new and useful Improvements in Traction-Wheels, ofgwhich the following is a'speeification: g

This invention relates to that class of traction wheels 4for automobilesand like uses', inf whichk the wheel is adapted for the dualfunctions ofa driving and steeringwheel; and the presentimprovement has for itsobject .to provide a simple and eiiicient structural formation andcombination of parts adapted to afforda strong and substantial drivingconnection between the power shaft and thewheel, with an avoidwhich atthe same -time affordsl al durable mechanism of a drivingand lsteeringwheel ofthe present type',l .all aswill hereinafter more'fully appear. ei p In the accompanying' drawinoszfFigure ,1, is al verticaly axialsection loa traction wheel.l and accessories, to which 4the present'invention is applied. Fig. 2 is adetail peru head connection. Fig. 3, isa vertical 'sec-` tionon line afm F ig. 1`, illustrating thelarrangement of the brake mechanism' of the spective view of theoperative levers &c.,'of said brake mechanism. i

Similar numerals of reference indicate 'like-parts in 'thediiferentviews. j Referring to the drawings, 1 re resents the usual. `Wheel hubAextending slig itly .bei `yond'y-thespokes Within the felly atitsin-'ner end and. having the usual enlargedbore,

eaehend toV forml shouldered recesses for the -nally coned"rings 2 and-3 forming parts of the tracks or .races for the usual series of conicalrolls 4 and 5, as usual. i

,Such thimble is formed with a screw tlireadroller bearing, hereinafterdescribed; while a cup shaped enlargement '6 the upper and lowerportions lof which constitute the pivot Vknuckles ,or jaws of thehereinafter described joint of said thinible with the stationary axle ofan automobile.

7 isa coned ring held in a longitudinally adjustable mannerupon theouter part of the tliimble `G by .a holding nut' screwing upon the outerend of the thimble as shown;`

such coned ring 7 .is the companion to the before described coned ring 2of the hub, and

between which coned rings the outer series of bearing rollers 4, arearranged.

8 is a coned ringarranged upon the thimble 6'near its inner end and heldlagainst longitudinal movement by abutment against the thimbleenlargement 6 as shown;'such coned ring 8 is t-he companion of thebefore described coned ring 3. of the hub, and between which rings theinner series of bearing rollersf arearranged. It will be observed thatthe cup shaped enlargement 6' of the thimble 6 is locatedl adjacent orcontiguous to the spokes within the felly so as to provide a compactarrangementf the parts.

- 9, is an end portion of the stationa-ry axle' of an automobile, orlike vehicle, formed withend knuckles or'jaws l0, in vertic."'illyseparated relation, and -to which corresponding knuckles or jaws 11 onthe cup shaped enlargement 6( of the tubular member or .thimble 6, 'arejournaled by pivot pins12, so that'the said thimble is capable of theusual pivoted adjustment on the stationary axle o f the vehicle ineffecting a steering adjustment z of the parts. For attainingsuchsteering adjust-ment' of the'thimble and traction wheel carried on.the same, theusual'lateral arm, not shown, will be providedon'said'lthiinble for .operative connection with 13", is thedriving orpower shaft-journaled j asteering- ,leverjconvenient to theoperator..ff.;"Yl
